quick ultrix questions

[Sam McCall]

hardware:  11/785
software:  ultrix 3.1

1.  what files absolutely have to be on the boot floppy, and
    how do i get the lsi-11 to believe that the floppy i've
    just created is a system volume?  (the error i get back
    is 'Volume "78X Console" is not a System Volume", or something
    like that).

2.  rmt bails out when doing a remote dump from a 4.3bsd system
    or a sun running 4.0.3 to an ultrix 3.1 host.  is this a known
    problem?  is there a patch or a workaround?

3.  are there any known difficulties/bugs with tset?  when i use
    it to set my term type while using ports on a dmf32, it seems
    to scribble all over my other settings (i.e. set me to upper case
    mode, set my output baud rate to 150 baud or sometimes, i think,
    0 baud, and other nastiness).  patches, workarounds or suggestions?
    (other than the standard 'don't use tset'.)

thanks,
